Question

Find the perimeter of a rhombus having a side length of 21 cm.
please

Answer 1

Answer:

Hence, value of perimeter of rhombus will be 84 cm

Step-by-step explanation:

In context to question asked,

We have to determine the perimeter of the rhombus.

As per data given in the question,

We have,

Side of rhombus = 21 cm

As we know that,

Rhombus is a quadrilateral whose all sides are equal.

Perimeter of Rhombus is nothing but sum of all the outer sides of the Rhombus.

As we have,

Formula for finding the Rhombus is $Perimeter = 4 \times sides$

So, for determining the value of perimeter we will put the value of side of rhombus in above formula,

Thus we will get,

$Perimeter = 4\times 21 = 84\:cm$

Answer 2

Answer:

The perimeter of rhombus is 84 cm.

Step-by-step explanation:

Given information,

The side length of rhombus is 21 cm .

We have to find out the Perimeter of rhombus.

All the sides of Rhombus are equal.

Hence,

The perimeter of rhombus will be side + side + side + side = 4 × sides

As we know that,

The perimeter of rhombus = 4 s

Where,

s is the sides length of rhombus.

By putting given values in the formula,

The perimeter of rhombus = 4 × 21

The perimeter of rhombus = 84

Hence,

The perimeter of rhombus is 84 cm.
